' To all 1071,0772, it may concern:

Be it known that we, JOsEPH DION and JOHN D. BELANGER, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Oil- CakeTrimmers; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Our invention relates to a novel construction in an oil cake trimmer,the object being to provide a device by means of which the soft oilyedges of linseed oil cake can be rapidly and neatly removed, andconsists in the features of. construction and combinations of partshereinafter fully described and claimed.

In the accompanying drawings illustrating our invention: Figure 1 is atop plan view of a machine constructed in accordance with our invention.Fig. 2 is a vertical transverse section of same on the line 22 ofFig. 1. Fig. 3 is a vertical longitudinal section on the line 3-3 ofFig. 1. Fig. 4 is a detail top plan view of one of the trimming knives.Figs. 5 and 6 are sections on the line 5-5 and 66 of Fig. 4respectively. Figs. 7 and 8 are respectively a detail top plan view anda side elevation of the sprocket chain and hooks for carrying the cakethrough the machine.

Our machine comprises a frame 1, preferably mounted on a platform 2, andcarrying hearings in which are ournaled four shafts 3, 4, 5 and 6 eachcarrying a pair of sprocket wheels 7 over which sprocket chains 8 aretrained. Above said shafts 3 and 4 is a table 9 the rear end of which israised as at 10. The oil cake is stripped by hand upon the raisedportion 10 of said table and is then laid upon the main portion 9 whereit is engaged by hooks 11 on said sprocket chains 8 and transported ashereinafter described. The links of said sprocket chains 8 are providedwith projecting lugs 12 and upon such lugs said hooks 11 are mounted.The latter con sist each of two plates 13 each having a raisedoverhanging portion 14 and secured together by 'means of the cross-piece15. Each of said plates is provided at one end with a perforationentered by one of said lugs and at its other end with a slot 16 enteredby a lug on another link. Said plates are each provided between thenends w th a large circular opening 17 in which an intervening lug isfreely movable. Extending above said table 9 is a frame 18 to which twospring-actuated levers 19 are pivotally secured. The lower ends of saidlevers 19 eX- tend into the path of the oil cake and are forced out ofsuch path by the oil cake which they act to hold down upon the table andin the path of planes hereinafter fully described. The portion of saidframe 13 above said lower end of said aprons, acts as a stop to preventmore than one oil cake from passing through the machine at one time.Pivotally mounted on each side of said table 9 below said frame 18 aretwo vertical crankshafts 20 engaged by spiral springs 21 to normallyhold. the horizontal arm 2 of each nor mally at the inner limit of itsmovement with relation to said table 9. Said arms 22 each carry what weterm a trimming plane 23 which is pivotally mounted thereon. Each ofsaid planes 23 consists of two parallel horizontal plates 24 connectedtogether by a vertical V-shaped plate 25 at one end, one leg of whichextends parallel with the inner edges of said plates 24 while the otherextends at an angle of about forty-five degrees thereto. A kmfe 26 restswith one face against the angular leg of said plates 25 and is held inposition by means of a shoulder 27 on the lower plate 24 and a set-screw28 mounted is the upper plate 24. Said upper plate 24 is provided withtwo parallel transverse slots 29 through which set-screws 30 pass whichenter screwthreaded openings in the flange 31 of a plate 32 which isthus adjustably mounted between said plates 24, and extends parallel tothe inner edges of the latter, its forward end being bent back to avoidbringing said end in contact with the oil cake.

The end of the crank arm 22 is bent upwardly and passes through bothsaid plates 24, its upper end being engaged by a spring 33 engaging theset-screw 28 to normally hold said planein the position indicated infull lines in Fig. 1, with relation to said crank arm. The lower plate24 carries two stops 34 and 35 which limit the pivotal movements of saidplane with relation to said crank arm.

The oil cake in passing, engages the forward end portions of the planes,thereby turning same on their pivots and automatically adjusting them sothat the knives thereof engage the forward ends of the cake and thenfollow the contour of the latter, thereby cutting ofi strips of givenwidth from the ends. The portion of the oil cake cut ofi is the softoily edge portion which is IIO displaced during the hydrauliccompression of the cake and said edge portions are returned to the pressand again compressed into cakes. The strips cut off by said planes dropinto receivers 36 whence they pass through tubes 37 to any desiredreceptacle or carriers.

The cakes after passing between the planes are carried to the end oftable 9 whence they drop upon a second slightly lower table 38. Thelatter is provided at its ends with bearings in which shafts 39 and 40are ournaled, each of which carries sprocket wheels over which a secondpair of sprocket chains 41 are trained, said chains 41 being of the sameconstruction as the sprocket chains 8 and carrying similar hooks 11which engage one end of the cake and carry same between a similar pairof planes 42 located one at each side of said table and mounted upon theupper ends of arms 43 pivotally mounted upon shafts 44 mounted upon theframe 1 below said table 38. Said arms 43 are actuated by springs 45 tohold the said planes 42 nor mally in the path of the oil cake. Oil cakesare generally of oblong shape, the long edges being parallel and theshort edges rounded or convex. Hence, it is unnecessary that said planes42 for trimming the long edges should have a pivotal motion in ahorizontal plane as is essential with the planes 28 for trimming therounded ends of the cake.

As the cake passes between the planes 42 the long edges of same aretrimmed and the cakes then delivered to a receiving frame 46 of anysuitable construction.

Our machine is driven by means of a driveshaft 47 below the platform 2which is geared to the shaft 5 by means of sprocket chains and wheels,and said shaft 5 is in turn geared to a shaft 48 by means of bevel gears49 and 50. The said shaft 48 is in turn geared to the shaft 39 by meansof sprocket wheels and chain.

Our device is very simple and efficient and saves a great deal of labor.

The particular forms of construction, and the size, proportion andarrangement of parts, above described and set out in the drawing, are tobe understood as capable of more or less variation without departingfrom the spirit of our invention and theyare to be taken simply asillustrative of the invention.

The table consists of two parts, one the upper level and the other thedepressed portion shaped somewhat like the outlines of the cakes to betreated. This depressed portion is associated with a frame, whichprevents any but the lower cake from passing under it, and the passageof the lower cake is resisted by downwardly projecting spring parts,which however give way and then serve as presser hands on the upper partof the cake to hold it down in position as it passes along the table.The hooks which engage the rear edge of the cake to pull it forward arearranged as shown, being pivotally secured at one end on the cross piecewhich holds two links of the sprocket chain together. These hooks aresecured midway on a like cross piece, but in large openings, and at theother end on a like cross piece by means of a slot. Thus, these hooksare given a length greater than that of a single link, or even two linksin the chain, and are yet arranged so as to freely pass around thesprocket wheels. This forwardly projecting portion of the hooks isarranged to receive the under part of the rear portion of the cake atthe time when it is about to be engaged by the hooks, and thus a certaingrip or hold of the cake is obtained, it being clamped in a certainsense between the hook proper and the forwardly projecting part thereof,as is indicated in Fig. 3.

The planes or cutters for removing the edges of the cake are pivotedupon an arm, which is itself pivoted, and the arm is elastically forcedtoward the cake. The plane itself is elastically supported, so that itmay swing slightly on its pivot, while at the same time being held incomparative parallelism with the cake, whatever the position of thesupporting arm may be as varied by the size or width of such cake. Thisarrangement of the cutter or plane is such as to make it perform itsfunctions effectually without regard to the width of the cake, andwithout regard to the irregularities of the cake, and to cut along theedge of such cake by a somewhat irregular path such as is proper toremove the somewhat irregularly projecting portions of the oil cake. Thecutters or planes which operate against the longer sides of the cake onthe second table are not mounted in the same Way, but it is obvious thatthe same kind of cutter could be used there as is used in the othercase. This cutter and the method of mounting it is an important part ofthe invention.
